Clothes in the drum 20 may be dried by the hot and dry air. The air, which is after drying the clothes, may become a high temperature and high humidity state and the high temperature and high humidity air in the drum 20 may be discharged to the outside of the drum 20 through the discharge flow path 81.

The clothes treating apparatus 1 may dry the clothes inside the drum 20 while repeating the above process.

The clothes treating apparatus 1 may include a discharge duct 50 forming the discharge flow path 81. The discharge duct 50 may include a filter duct 51 forming an outlet, through which the air inside the drum 20 is discharged, and in which the filter device 12 and the sheet receiving device 90 are arranged, and a guide duct 52 guiding air from the filter duct 51 to the heat exchangers 61 and 62.

The heat exchangers 61 and 62 may include an evaporator 61 and a condenser 62. Although not particularly shown in the drawing, a compressor and an expansion valve may be provided in the lower portion of the cabinet 10. Accordingly, the evaporator, condenser, compressor, and expansion valve may form a heat pump. According to one embodiment of the present disclosure, the clothes treating apparatus may include the heat pump, but is not limited thereto. The clothes treating apparatus may include a gas-type clothes treating apparatus and an electric heater-type clothes treating apparatus.

Referring to FIGS. 3 to 5 , the clothes treating apparatus 1 may include a sensing device 200. The sensing device 200 may be put into the drum 20 to assist at least one of washing or drying clothes when the clothes treating apparatus 1 operates. For example, the sensing device 200 used in a washing machine may collide with clothes to remove foreign substances from clothes. In addition, the sensing device 200 may check a degree of washing by sensing a turbidity of water during the washing. The sensing device 200 used in a clothes dryer may generate a space between the clothes so as to allow the clothes to be stretched without clumping during the drying. The sensing device 200 may check a degree of drying by sensing a temperature and a turbidity within the drum 20. However, the sensing device 200 is not necessarily provided in the clothes treating apparatus 1 and may be provided as a separate component.

The sensing device 200 may be referred to as a sensor ball 200. However, although the sensing device 200 is shown in a spherical shape in the drawing, it is not limited thereto. Accordingly, the sensing device 200 may include various shapes. For example, the sensing device 200 may include a shape such as a cylinder, a rectangular parallelepiped, or a regular hexahedron.

For convenience of description, a direction, in which first mounting grooves 211 are arranged, is defined as a vertical direction and a direction in which second surfaces 202 are arranged is defined as a front and rear direction. However, the arrangement direction of the components below is not limited thereto.

The sensing device 200 may include a first surface 201, the second surface 202, a third surface 205, an inner support member 203, and an internal space 204.

The first surface 201 may form one surface of the sensing device 200. The first surface 201 may be formed on both sides with respect to the second surface 202. That is, the first surface 201 may be provided in plurality.

The second surface 202 may be provided on a surface perpendicular to the first surface 201. The second surface 202 may also be provided in plurality on both sides with respect to the first surface 201. A second mounting groove 212 may be formed between the first surface 201 and the second surface 202.

The third surface 205 may be provided between the first surface 201 and the first mounting groove 211. The third surface 205 may be provided in plurality.

The inner support member 203 and the inner space 204 may be provided inside the sensing device 200. The inner support member 203 may support the inner space 204 of the sensing device 200 to prevent a plurality of components provided inside the sensing device 200 from being damaged. An empty space may be formed in the inner space 204 of the sensing device 200 to perform a buffering effect when the sensing device 200 receives impact.

In the sensing device 200, a pipe member 220, a magnet 230 moving in a space of the pipe member 220, and at least one sensor 240 may be provided. That is, the sensing device 200 may include the at least one sensor 240 configured to measure a temperature or a humidity in the drum 20.

The pipe member 220 may include a guide member 221, a reinforcing member 222, and a cover member 223.

The guide member 221 may form a passage extending in the vertical direction to allow the magnet 230 to move therein. Because the magnet 230 moves in the vertical direction in the guide member 221, electromagnetic energy may be generated. The generated electromagnetic energy may supply energy used in at least one sensor 240 and a communicator 250. Therefore, it is possible to save energy. That is, energy harvesting may be possible.

The guide member 221 may be provided in the shape of a hollow cylinder. However, the shape of the guide member 221 is not limited thereto and may include various shapes.

In addition, the sensing device 200 including the magnet 230 may be easily mounted on the holder 100 to be described later. That is, when the sensing device 200 is mounted on the holder 100, the magnet 230 may be arranged adjacent to the holder. However, the moving direction of the magnet 230 is not limited to the vertical direction, and as the sensing device 200 moves within the drum 20, the magnet 230 may move in a corresponding direction.

The reinforcing member 222 may be arranged outside the guide member 221. That is, the reinforcing member 222 may be provided in a circular shape on an outer circumference of the guide member 221. The reinforcing member 222 may increase a strength thereof on the outside of the guide member 221.

The reinforcing member 222 may be provided at a center of the pipe member 220. Therefore, it is possible to allow a center of gravity of the sensing device 200 to be positioned at a center of the ball. Accordingly, the sensing device 200 may move freely in the drum 20 without being biased to either side. In addition, the sensing device 200 may maintain the center of gravity even when the first mounting groove 211 is coupled to a mounting protrusion 110.

The cover member 223 may be provided at an upper end and a lower end of the pipe member 220, respectively. The cover member 223 may be coupled to the upper and lower ends of the guide member 221, respectively. That is, the cover member 223 may be provided in plurality. The cover member 223 may be arranged adjacent to the first mounting groove 211 or the second mounting groove 212. Accordingly, the sensor 240 may be arranged adjacent to the first mounting groove 211 or the second mounting groove 212 to sense the temperature or humidity in the drum 20. The cover member 223 may prevent the magnet 230 from being separated from the guide member 221.

The sensing device 200 may include at least one sensor 240. At this time, if the clothes treating apparatus 1 is a washing machine, the sensor may be a turbidity sensor. The turbidity sensor may measure a turbidity of washing water. If the clothes treating apparatus 1 is a clothes dryer, the sensor 240 may include at least one of a temperature sensor 241 or a humidity sensor 242. That is, the sensor 240 may sense at least one of a temperature or a humidity in the clothes dryer. The at least one sensor 240 may include a non-contact sensor.

The sensing device 200 may include the internal communicator 250. Accordingly, information obtained by the sensor 240 may be transmitted to the clothes treating apparatus 1 through communication with the clothes treating apparatus 1. In addition, the sensor 240 may include the communicator 250 configured to communicate with the clothes treating apparatus 1 by detecting attachment or detachment to the holder 100 described later. The communicator 250 may include a printed circuit board (PCB).

The sensor 240 and the communicator 250 described above are only examples, and the types of the sensor 240 and the communicator 250 are not limited thereto.

The sensor 240 and the communicator 250 may be formed at the upper end or the lower end of the pipe member 220. That is, the sensor 240 and the communicator 250 may be arranged on the cover member 223. The sensor 240 may be arranged adjacent to the first mounting groove 211 or the second mounting groove 212 so as to sense the temperature or humidity in the drum 20. However, positions of the at least one sensor 240 and the communicator 250 are not limited thereto and may be placed in various positions such as inside or outside the sensing device 200. In addition, although two sensors 240 are shown, various numbers such as one complex sensor or three or more sensors may be provided. The number of communicators 250 is not limited to one and may be provided in various numbers.

The sensing device 200 may include the mounting groove allowing the sensing device 200 to be mounted on the clothes treating apparatus 1. The mounting groove may include the first mounting groove 211 and the second mounting groove 212.

The first mounting groove 211 may be recessed inward from an outer circumferential surface of the sensing device 200 so as to be coupled to the mounting protrusion 110 of the holder 100. The first mounting groove 211 may be provided in plurality along the vertical direction. The first mounting groove 211 may be provided between the plurality of third surfaces 205. The first mounting groove 211 may be provided in plurality. Because the first mounting groove 211 is coupled to the mounting protrusion 110, the sensing device 200 may be stably coupled to the holder 100.

The second mounting groove 212 may be recessed on the second surface 202 to be mounted on a partition wall 133 of the holder 100. The second mounting groove 212 may be recessed inward from the second surface 202 of the sensing device 200. The second mounting groove 212 may be provided in plurality along the front and rear direction. The second mounting groove 212 may be provided in plurality. The second mounting groove 212 may be provided between the second surface 202 and the third surface 205. Because the second mounting groove 212 is coupled to the partition wall 133, the sensing device 200 may be stably coupled to the holder 100.

FIG. 6 is a view illustrating some components of the clothes treating apparatus 1 shown in FIG. 1 . FIG. 7 is an enlarged view of the clothes treating apparatus 1 shown in FIG. 6 . FIG. 8 is a front view of the clothes treating apparatus 1 shown in FIG. 6 .

Referring to FIGS. 6 to 8 , the lifter 21 may include a plurality of lifting members 21 a and 21 b and the holder 100. The lifter 21 may be provided in plurality in the clothes treating apparatus 1.

The plurality of lifting members 21 a and 21 b may protrude from an inner circumferential surface of the drum 20 to allow the clothes to move inside the drum 20. The plurality of lifting members 21 a and 21 b may include a first lifting member 21 a and a second lifting member 21 b. The first lifting member 21 a and the second lifting member 21 b may be spaced apart from each other along a rotation axis direction A of the drum 20.

The holder 100 may be provided inside the drum 20. Therefore, because the sensing device 200, which is stored inside the drum in the non-operation state, is put into the drum 20 in the operation state, the sensing device 200 may assist the washing or drying without a user's additional motion.

The holder 100 may be arranged between the plurality of lifting members 21 a and 21 b along the rotation axis direction A of the drum 20. That is, the holder 100 may be arranged between the first lifting member 21 a and the second lifting member 21 b. Because the holder 100 is arranged between the plurality of lifting members 21 a and 21 b, an area of a space except a space in which the clothes are lifted may be increased, and because the holder 100 also serves as a lifter, the drying effect may be improved. If the clothes treating apparatus 1 is a washing machine, the washing effect may be increased due to the arrangement of the holder 100.

The holder 100 may include a base 101, the mounting protrusion 110, and a seating member 120.

The base 101 may be provided at the bottom of the holder 100. The mounting protrusion 110 may be provided above the base 101. A portion of the base 101 may form the seating member 120. The base 101 may include a material having a magnetic force. Accordingly, the sensing device 200 including the magnet 230 may be mounted on the holder 100. In addition, the base 101 may include an electromagnet (not shown), and accordingly, the sensing device 200 may be attached to or detached from the holder 100 by controlling the electromagnet. For example, in response to turning on the electromagnet, the sensing device 200 may be mounted to the holder 100 and in response to turning off the electromagnet, the sensing device 200 may be separated from the holder 100. Therefore, the sensing device 200 may be easily separated from the holder 100 without an additional action such as physically removing the sensing device 200 by a user.

The mounting protrusion 110 may protrude from the base 101 toward the center of the drum 20. The mounting protrusion 110 may be coupled to the mounting groove of the sensing device 200. Accordingly, the sensing device 200 may be mounted and stored in the drum 20 when the clothes treating apparatus 1 is not in operation. The mounting protrusion 110 may be coupled to the first mounting groove 211 of the sensing device 200. One first mounting groove 211 among the plurality of first mounting grooves 211 may be coupled to the mounting protrusion 110.

The mounting protrusion 110 may extend along the rotation axis direction A of the drum 20. Therefore, the user can mount the sensing device 200 not in the middle of the holder 100 but in a region adjacent to the first lifting member 21 a or the second lifting member 21 b. In addition, because the mounting protrusion 110 extends in the rotation axis direction A of the drum 20, the mounting protrusion 110 may serve as the lifter. The first mounting groove 211 of the sensing device 200 may correspond to an extending direction of the mounting protrusion 110. That is, the first mounting groove 211 may be formed to be mounted along the rotation axis direction A of the drum 20.

The seating member 120 may be formed on the base 101. Particularly, the sensing device 200 may be seated on the seating member 120 in response to mounting the sensing device 200 to the holder 100. The seating member 120 may be provided on both sides of the mounting protrusion 110. That is, the seating member 120 may be provided in plurality. Because the seating member 120 is provided, the sensing device 200 may be more stably mounted on the holder 100. The sensing device 200 may not be mounted only in the region where the seating member 120 is formed, and the sensing device 200 may also be mounted in a region where the seating member 120 is not formed.

Because the clothes treating apparatus 1 includes the holder 100, it is possible to easily store the sensing device 200 and to prevent the sensing device 200 from being lost. Accordingly, it is possible to continuously use the sensing device 200 so as to increase the efficiency in the washing cycle and the drying cycle.

FIG. 8 is view illustrating a state in which the sensing device 200 mounted to the holder 100 is separated from the holder 100 in the clothes treating apparatus 1.

When the clothes treating apparatus 1 operates, the drum 20 may rotate. When the drum 20 rotates, the holder 100 on which the sensing device 200 is mounted may reach the highest position. At this time, because gravity acts on the sensing device 200, the sensing device 200 may fall down due to its own weight. That is, the sensing device 200 may be directed toward a center direction B of the drum 20. The separated sensing device 200 may assist at least one of washing or drying while moving in the drum 20. Therefore, the self-weight of the sensing device 200 may be greater than or equal to the magnetic force between the sensing device 200 and the holder 100 so as to allow the sensing device 200 to fall due to the self-weight of the sensing device 200. Therefore, the sensing device 200 may be easily separated from the holder 100 without an additional action such as physically removing the sensing device 200 by a user.

When the sensing device 200 is mounted, the sensor provided therein may detect that the sensing device 200 is mounted, through at least one of the change in the magnetic field or a detection sensor, and communicate information related thereto with the clothes treating apparatus 1. In addition, when the sensing device 200 is separated, the sensor provided therein may detect the separation of the sensing device 200 and communicate information related thereto with the clothes treating apparatus 1.

That is, the sensing device 200 may be separated from the holder 100 by a rotational force of the drum 20. At this time, the rotational force of the drum 20 may be greater than or equal to the magnetic force between the sensing device 200 and the holder 100 so as to allow the sensing device 200 to be separated by the rotational force of the drum 20. Therefore, the sensing device 200 may be easily separated from the holder 100 without an additional action such as physically removing the sensing device 200 by a user.

In the drawing, the sensing device 200 is arranged in the lateral direction of the holder 100 opposite to the rotational direction C of the drum 20, but is not limited thereto. That is, the mounting protrusion 110 may be formed on the right side of the holder 100 and thus the sensing device 200 may be arranged on the right side of the holder 100. In this case, the sensing device 200 may be separated by the self-weight of the sensing device 200 rather than the rotational force of the drum 20. Therefore, the sensing device 200 may be separated in response to the mounting protrusion 110 facing downward.
